 The Tulik Lake relocatable aquatic field site is located in the foothills of the Brooks Range on the Alaskan tundra. It covers one and a half square kilometers and has a mean depth of seven meters. Automated sensors installed on a buoy system along with groundwater wells and a nearby MET station collect data about the lake and the atmosphere. Observational sampling of aquatic organisms, biogeochemical cycling and other physical properties of the lake are also conducted at this site.
